INK-ERDICATOR.

aiaaeor.

Specification of Letters Patent.

Application led November 11, 1914. Serial No. 871,498. i

To all whom t may concern:

Be it known that 4I, KENNETH W. MAG- PHERsoN, a citizen of the United States, and :president of Palmyra,- in the county of Wayne and State of New York, have invented certain new and useful improvements in Ink-Eradicators, of which the following is a specification.

My invention relates to ink eradicators, and the main object thereof is to provide a container for each of the two liquids used in ink eradication and forming, jointly, a unit adapted to be carried in the pocket, handbag, or the like.

A further object is to provide each container with a valve, the stem of which projects beyond the container, whereby the said liquids may be applied directly to the ink which it is desired to eradicate in the manner of-writing.

A further object is to combine the container with any one of the usual implements carried by a person in his pocket, such asa fountain pen, a pencil, a knife, a scratcher, or the like, in such manner as to enable a person to use each liquid at will.

A further object is to provide means for locking the container, in such combined use, in either of its two operative positions; and

further objects are to provide such devices.

which are simple in construction and use, which are well adapted to the purpose for which they are designed, which may be made very ornate, which are compact and always ready for use, and which are comparatively inexpensive.

My invention is fully described in the following specification, of which the accompanying drawings form a part, in which llike reference characters indicate like parts in each of the views, and in which Figure lis a side view of my invention applied to a fountain pen; Fig. 2 is` an enlarged, sectional, detached, view thereof; and Fig. 3 is a detached view of a valve `which l employ.

gitudinal, bore 10 at each end, and two diametrically arranged bores 1l in the flange 5, and a longitudinally arranged slot 12 in the position of each bore 11.

The cup 8 has a chamber 13 therein of conical formation at 14 to form a seat for a conical valve 15 and the stem l16 of which is grooved or flattened at 17 and slidable in a bore 18 of said cup, a coil spring 19 being interposed between the Vvalve and correspending `end of the block 4 and guided by means of a rod 20 resting on the bore 10 of said block and a` bore 21 in said valve, and the stem 16 projects slightly beyond the end of the cup 8. f

The cup 9 has a chamber 22 therein of conical formation at 23 to form a seat for a conical valve 24 and the stem 25 of which is grooved or attened at 2 6 and slidable in a` bore 27 of said cup, a coil spring 28 being interposed between the valve and correspending end of the block 4 and guided by means of a rod 29 resting in the bore 10 of said block and. a bore 30 in said valve, and the stem 25 projects slightly beyond the end of the cup 9.

'llo fill the cups with the desired liquids, one'cup is unscrewed from the block 4, the valve preventing the liquid dropped into saidv cup-from escaping therefrom, or the erson lling the same may press a finger rmly against the outer end thereof to prevent leakage, the open end of the cup being uppermost, and, when filled, the block 4 may be screwed thereinto, and, this being repeated for the other cup, the device is ready for use.

I will provide means for distinguishing one cup from another, such as the numerals shown, whereby the particular liquid contained therein may be determined, and it will be seen that, if the Valve stein of either of the cupsage placed aglainst the ink spot to be eradica ed and slig t pressure exerted on the container downwardly toward the ink spot, the valve is raised from its seat and the liquid passes through the vent of the cup,

valong the grooved or iattened side of the valvestem, and onto the ink spot, the degree of pressure determining the amount of liquid so discharged. After one liquid has been s'o discharged and sucient time al lowed for the chemical action thereof with the ink, the spot may be blotted in the usual manner and the other liquid used to entirely corrode and remove the ink spot.

ln Fig. 1 l have sho'wn two spring arms 31 secured to the cap 32 of a fountain pen Patented Sept. i4, i915.

los l 33, and each of which is provided 'with a trunnion or pintle 34 resting within the corresponding bore 11 of the flange 5, thus permitting revolution of the container in the frame so formed, and I have shown a rib 35 on the inner surface of each arm adapted to'enter a corresponding slot l2 in said flange to lock the container against accidental displacement, but any other means for locking the container may be employed, and said container may be mounted upon other articles than fountain pens, and in any desired manner, but the combination of an ink eradicator carrier with a fountain pen is logical to say the least; I may also, as shown, secure-a clip 36 to the arm or arms 31 to hold the combination .in the pocket, Aand `which clip may be of any desired orm. A

The device, as illustrated, is of the approximate diameter of the fountain pen cap, and of inconsiderable length when the advantages are .considered,but, obviously, I do not limit myself to the size, shape, material, or specific construction of the container, nor to its particular combination with any other article, although I do claim its use as shown.

Having fully described my invention, what I claim as new, and desire to secu're by Letters Patent, is:-

1. A device of the class described, comprising a block provided with an axial bore at each end and an external screw thread at valve slidably mounted on each rod providedwith a stem closely fitting within the reat each end and an external screw thread at each end, a cup detachably engaged with each threaded end provided with a conical outer end and a discharge bore in said end, a rod seated in each axial bore, a conical valve slidably mounted on each rod providedl with a stem closely lfitting within the @respective discharge bore and iiattened at one side intermediate its ends, and a coil spring -4 interposed between each valve andthe respective block end.

3. A device of the class described, comprising a central block, a cup in detachable connection with each end thereof having a discharge bore therein, a valve in each cup provided withl a stem projecting beyond said cup, yielding means for `maintaining said valves against their seats, a fountain pen cap, spring arms secured thereto and provided With lateral trunnions arranged on the same transverse aXis and with ribs adjacent said trunnions, said block having diametrically arranged lateral bores therein adapted to receive the respective trunnions and having slots therein adapted to receive said ribs, whereby said device may be reversed endfor end and be locked in each position.

In testimony whereof I have signed my name to this specification inxthe presence of two subscribing Witnesses.
